Bright Fluorescent Biosensors for Diacylglycerol

Downward DAG starts out bright and decreases in fluorescence when diacylglycerol levels increase. This assay is easily detected on fluorescence plate readers and helps with imaging cells that have low expression efficiency.

Upward DAG starts out dim and increases in fluorescence when when diacylglycerol levels increase. This DAG assay is easily detected on fluorescence plate readers or imaging systems.

DAG Assay Performance

Off the shelf kits include the DAG sensor in BacMam, a BSL-1 viral vector for efficient delivery to most cell types. Purified BacMam, AAV, Lenti vectors by request.

  • Easily detectable on plate readers or imaging systems
  • Consistent well-to-well expression
  • High signal-to-noise ratio

Red DAG sensor multiplexed with a green cAMP sensor indicates dose-dependent signaling via a calcitonin receptor.

In HEK 293 cells over-expressing the P2Y11  receptor, ATP produces changes in both DAG and Ca2+, consistent with activation of Gq-coupled GPCR signaling. UTP produces no DAG response, indicating that the Ca2+ change is independent of Gq.

Expression in human islets is pretty superb, after 18 hours of incubation. An excellent probe!
